In and around Pays des Abers
In addition to the museum of rockweed harvesters in Plouguerneau, do not miss the world's highest stone lighthouse, Phare de l'Ile Vierge. It is now listed as a historical monument.
If you're feeling like a coastal stroll, head to Landeda. The Sainte-Marguerite dunes line the coastal trail at the mouth of the Aber-Benoit River.
